UTLX X design dimensions

Earl Tuson

The 1906 CBD has plans for 6,000 gal UTLX X design tank cars:


This drawing shows the bolster centers to be 17’, and the 5 horizontal course 76” ID tank length to be 25’
(26’6” over the heads.)

PBL makes very high quality Sn3 equipment. Their 6,000 gallon tank molding is used in their Type V kit
and their modified, wide frame, Type X (converted by the prototype from normal standard gauge Type X
cars.) However, the PBL 3 horizontal course tank is ~77.5” OD but 26’6” long (28’ over the heads,) with
19’ bolster centers.

Can anyone offer insight into these apparent discrepancies?
